Mdmp 1302 01 American Powertrain Five Speed Transmission 1967 Mercury

Our candidate for the modern five-speed transmission swap is this ’67 Mercury Cougar that’s still lugging around its original slushbox. Although it has it’s own unique look, the Cougar is mostly first-generation Mustang under the sheetmetal. Here, Roush Yates Performance Products shop manager, Jeff Paxton, and the crew from American Powertrain, are busy pulling the original transmission and driveshaft.
